v2.4.194 - 2024-06-21

Included in the release

  • A few issues fixed
  • Some clean-up of the duplicated methods after the latest Converters have been merged
  • Avoiding the duplication of Event tags in Attributes
    ➡️ When an Event is tagged with a specific tag, it implies all the Attributes contained in this Event are implicitly tagged with the same tag. We do not need to explicitly tag all the Attributes with the same tag in that case.
    ❌ : As a naive approach, we were looping through Marking Definitions to tag individually each Attribute when there was a reference between the corresponding STIX object and Marking Definition
    ✅ Now we first check if a given Tag is already attached to the Event before attaching it to an Attribute
